SELF-E J'ECTING PENI-IOLDER.

Specification of Letters Patent.

Patented June 16, 1908.

Application filed October 12, 1907. Serial No. 397,187.

To all whom it may concern:

Be it known that I, EDWARD S. BROWNING, a citizen of the United States, residing at Boone, in the county of Boone, State of Iowa, have invented certain new and useful Improvements in Self Ejecting Penholders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make-and use the same. I

This invention has relation to that class of penpoint ejecting penholders in which the pen is ejected from the pen-stock by pressing upon pen-ejecting means extending from the base of the penstock.

It is the object of this invention to provide means that will greatly simplify the construction and mode of operating of penholders of the type or kind specified, and render the same more efficient than heretofore, in that, inter alia, the means for holding the pen in the holder is not modified or interfered with to make way for the pen-ejecting means.

In order that those skilled in the art to which my improvements relate may fully understand its construction and manner of operation, I will proceed to describe the same in detail, reference being had to the annexed drawings, forming a part of this specification, and in which like characters of reference indicate like parts or features, as the case may be, wherever they occur.

Of the said drawingsFigure 1 is a plan of a penpoint-ejecting penholder with my improvements applied. Fig. 2 is a longitudinal sectional view some of the parts being represented in elevation. Fig. 3 is a view of the blank from which the pen-retainer is formed, shown in developed form. Fig. 4 is a perspective view of the pen-retainer in complete form.

In the drawings 1 designates the penstock, constructed as a barrel, having a removable forward finger portion 2, telescopically secured to the barrel 1, the forward part of the end portion 2 being reduced in diameter, and provided in its forward extremity 3 with the pen-clamp to be presently more fully explained. The finger portion 3 is provided on its upper side, from a point near its forward end with a slot, 5, extending rearward nearly as far as the rear end of the penpoint will reach when in position.

6 designates a plug of lesser diameter than the interior of the pen-barrel 1, in the rear end of which latter it is introduced and the end of the barrel crimped around it, as shown. From the forward end of the plug 6 in the barrel there extends a wire rod 7 having an upturned notched end 8 that extends through the slot 5 and is held in position thereby, which slot is adapted to engage the rear end of the notches in the rod, and keep it in position to engage the rear end of the penpoin and push it out of the holder.

The forward end of the finger portion 3 of the penstock is reduced, so as to form a shoulder 9 where the barrel 1 joins the part 2.

Surrounding the rod 7 between the inner end of the plug 6 and the shoulder 9 is a helical spring 10 which bears at the rear end against the inner end of the plug and at its forward end against a washer 15, of suitable material resting against the shoulder 9.

11 designates a blank which is adapted to be bent into nearly cylindrical form, as shown, so as to form a desirable clamp 12 for the pen in the forward end of the penstock, as is usual. The central tongue 16, is bent down at its extremity, and projected through a small slot or perforation 17, in the bottom oil the finger portion to hold the latter in ace.

p The points 18 18 at the forward corners on the upper side of the pen-clamp are bent down to facilitate the introduction of the penpoint. The slot formed between the side edges of the penclamp afford a passage for the upturned end 8 of the rod in ejecting a en. The rod will be returned by the action 0 the spring 10. Y

In the operation of my invention, with the en in the penstock, as shown, by pushing forward on the protecting end of the plug 6, the rod 7 will be forced forward against the stress of the s ring 10 and the pen will be pushed out 0' place. Upon releasing the plug the latter and the rod 7 will be moved back to normal position ready for the insertion of a new pen in the holder.

What is claimed is l. The finger end of a penholder provided at its forward end with a slot at the top and bottom, combined with a penclamp having a tongue at its bottom projected through the said bottom slot, and having a slot extended along its top, downwardly bent corners at the sides of the front end of the edges, a enejecting means to operate in the slot o the finger end and between the upper edges of the penclamp.

2. The combination with the penstock I consisting of a barrel, a reduced forward end its upper forward part, of the pen-clam the plug in the rearward part of the barre having thelatter crimped thereon, a'rod extending from the inner end of thelplug to theforward end ofthe penstock and having anupturned end extending through said slot behind the rear end of the penpoint, and a helical spring surrounding said rod and hearing at its rear end against the forward end of the plu and at its forward end against said shoul er.

In testimony whereof, I affix my signature, in presence of two witnesses.

EDWARD S. BROWNING.
